Study Evaluating Safety and Efficacy of JCAR017 in Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)

Running, not enrolling · Phase 1/Phase 2

Conditions studied: Leukemia, Lymphocytic, Chronic, B-Cell, Lymphoma, Small Lymphocytic

In brief

This is a Phase 1/2, open-label, multicenter study to determine the efficacy and safety of JCAR017 in adult subjects with relapsed or refractory CLL or SLL. The study will include a Phase 1 part to determine the recommended dose of JCAR017 monotherapy in subjects with relapsed or refractory CLL or SLL, followed by a Phase 2 part to further assess the efficacy and safety of JCAR017 monotherapy treatment at the recommended dose. A separate Phase 1 cohort will assess the combination of JCAR017 and concurrent ibrutinib. Another separate Phase 1 cohort will assess the combination of JCAR017 and concurrent venetoclax. In all subjects, the safety, efficacy, and pharmacokinetics (PK) of JCAR017 will be evaluated.

You may qualify if…

• Diagnosis of:
• CLL with an indication for treatment based on the Investigator's opinion and measurable disease, or
• SLL (lymphadenopathy and/or splenomegaly and < 5×10\^9 CD19+ CD5+ clonal B lymphocytes/L [< 5000/µL] in the peripheral blood at diagnosis with measurable disease that is biopsy-proven SLL)
• Subjects (other than those in the ibrutinib + JCAR017 combination therapy and DEME cohort) must have received and failed Bruton tyrosine kinase inhibitor (BTKi) treatment or have been deemed ineligible for BTKi therapy.
• Subjects in the JCAR017 monotherapy cohorts must have received previous treatment as follows:
• Monotherapy cohorts EXCEPT DEME cohort: Subjects with CLL or SLL and high-risk features must have failed at least 2 lines of prior therapy.
• Monotherapy cohorts EXCEPT DEME cohort: Subjects with CLL or SLL and standard-risk features must have failed at least 3 lines of prior therapy.
• DEME cohort ONLY: Subjects with relapsed or refractory CLL or SLL, irrespective of cytogenetic risk features, must have received at least 2 lines of prior therapy including a BTKi and a BCL2i.
• Subjects in the ibrutinib + JCAR017 combination therapy cohort must either:
• be receiving ibrutinib and progressing at the time of study enrollment
• be receiving ibrutinib for at least 6 months with a response less than complete response/remission (CR) and have high-risk features as defined in inclusion criterion 5a
• have BTK or PLCgamma2 mutations per local laboratory assessment, with or without progression on ibrutinib
• have previously received ibrutinib and have no contraindications to restarting ibrutinib
• Eastern Cooperative Oncology Group performance status of ≤ 1
• Assessed by the Investigator to have adequate bone marrow function to receive lymphodepleting chemotherapy
• Adequate organ function, defined as:
• Serum creatinine ≤ 1.5 × age-adjusted upper limit of normal (ULN) OR calculated creatinine clearance > 30 mL/min
• Alanine aminotransferase ≤ 5 × ULN and total bilirubin < 2.0 mg/dL (or < 3.0 mg/dL for subjects with Gilbert's syndrome or leukemic infiltration of the liver)
• Adequate pulmonary function, defined as ≤ Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 dyspnea and saturated oxygen (SaO2) ≥ 92% on room air
• Adequate cardiac function, defined as left ventricular ejection fraction ≥ 40% as assessed by echocardiogram or multiple uptake gated acquisition scan performed within 30 days prior to determination of eligibility
• Subject either currently has central vascular access or is a candidate to receive central vascular access or peripheral vascular access for leukapheresis procedure.
• If prior CD19-targeted therapy has been administered, subject must have CD19-positive disease confirmed by immunohistochemistry or flow cytometry since completing the prior CD19-targeted therapy.
• Subjects in ibrutinib + JCAR017 combination cohort must have progressed on a BTKi and have received prior therapy with venetoclax
• Subjects in venetoclax + JCAR017 combination cohort must:
• have failed at least 1 prior line of therapy, including failed BTKi therapy or have been deemed ineligible to receive BTKi

You may not qualify if…

• Subjects with known active central nervous system (CNS) involvement by malignancy. Those with prior CNS disease that has been effectively treated will be eligible if treatment was completed at least 3 months prior to enrollment with no evidence of symptomatic disease and stable abnormalities on repeat imaging.
• History of another primary malignancy that has not been in remission for at least 2 years. (The following are exempt from the 2-year limit: nonmelanoma skin cancer, completely resected stage 1 solid tumor with low risk for recurrence, curatively treated localized prostate cancer, cervical carcinoma in situ on biopsy or a squamous intraepithelial lesion on Pap smear, and in situ breast cancer that has been completely resected.)
• Subjects with Richter's transformation
• Prior treatment with any gene therapy product
• Active hepatitis B, active hepatitis C, or active human immunodeficiency virus (HIV) infection
• Systemic fungal, bacterial, viral, or other infection that is not controlled
• Presence of acute or extensive chronic graft versus host disease (GVHD)
